IMPROVEMENT IN LAST-BLOCK FASTENERS.

Specification forming part of Letters Patent No. 142,603, datedSeptember 9, 1873; application filed July 25, 1873.

To all whom it may concern:

Be it known that I, LUTHER S. WRIGHT, of Groton, in the county ofTompkins and State of New York, have invented certain new and usefulImprovements in Shoe-Lasts; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form. partof this specification.

My invention relates to improvementsin lasts; and the invention consistsin securing the block or instep-piece by means of a pivoted. claspdevice, so that the block may be attached to the last or removedtherefrom with the greatest facility and be secured in position withoutthe use of nails, or screws, or other device, as hereinafter more fullyset forth.

In the accompanying drawing, Figure 1 is a plan view of a last, showingmy improvement. Fig. 2 is a side elevation with a portion cut away toshow the pivoted clasp de-.

vice.

Arepresents a last; 13, the block or insteppiece; and O, the claspingdevice. The block 13 has on its forward end a stud or projecting pin,which fits ina corresponding hole in the last, and the rear end of blockB is out with a longitudinal groove, extending a short distance from therear end, and a lateral groove or notch, 1), extending across the rearend of block 13. The clasp (J is a piece of metal, the lower end ofwhich is pivoted to the last A by a pivot-bolt, a, so as to move backand forth in the longitudinal groove formed in block B, and in a similargroove formed in the last A. The clasp O is also provided with lateralprojections or cross-pieces D, and its upper portion is shaped into ahandle, convenient for operation. y

The operation of my improved device is as follows: When it is desired toattach the block or instep-piece B, it is simply placed in the requiredposition, and the pivoted clasp O pushed forward until the crosspiece Drests in the notch 12, by which operation block B is firmly secured inposition. When it is desired to remove the block, all that is necessaryis to push back the clasp O.

Whatv I claim as my invention, and desire to secure by Letters Patent,is

l. The pivoted clasp O, or its equivalent, for the purpose specified.

2. The combination of the pivoted clasp G, last A, and block B,substantially as and for the purpose specified.

In testimony that I claim the foregoing I have'hereunto set my hand andseal.
